Currently, this test detects EGFR mutations in NSCLC patients whose tumors harbor the exon 18 (p.(Gly719Ala/Cys/Ser)) substitutions, exon 19 deletions, exon 20 insertions and substitutions (p.(Thr790Met), p.(Ser768Ile)) and exon 21 substitutions (p.(Leu858Arg), p.(Leu861Gln)), but not any other EGFR mutations (Tables S5 and S6) [20]. The gene discussed is EGFR; the disease is non-small cell lung carcinoma.
